Backend Team Lead — Ruby on Rails

We operate an edge-to-cloud video AI platform used in live environments today. Edge nodes run on NVIDIA Jetson and process camera streams in real time. The cloud stack delivers stable APIs, WebSockets for live updates, and integrations with public-safety and enterprise systems. Your work will extend an active codebase, improve latency and reliability, and ship new features on a steady cadence.

Role

Own technical design and delivery quality for complex Rails systems. Turn business goals into pragmatic architecture; coach engineers; keep performance, security, and operability non-negotiable.

What you’ll lead

• Service architecture : API gateway, Rails API services, background workers, websockets.
• Data plane : durable eventing, queues, back-pressure, exactly-once where it counts.
• AuthN / Z and policy : JWT, mTLS, RBAC / ABAC, OPA / Rego policy checks.
• Data stores and models : PostgreSQL schema design, partitioning, migrations, indexing.
• Caching and realtime : Redis for cache / pubsub; ActionCable or alternative WS hub.
• Integrations : REST / XML adapters to external agencies and enterprise systems.
• Observability : metrics, logs, traces, red / black dashboards, SLO burn alerts.
• CI / CD and environments : build pipelines, artifact signing, staged releases, rollbacks.
• Reliability : incident response, on-call rotation, postmortems, runbooks.
